GENERAL DESCRIPTION

The T48 Controller accepts signals from a variety of temperature sensors (thermocouple or RTD elements), while the P48 Controller accepts either a 0 to 10 VDC or 0/4 to 20mA DCinput signal.Bothcontrollerspreciselydisplay the process, and provide an accurate output control signal(time proportional or linear DC) to maintain a process at the desired control point. The controllers’ comprehensive programming allows themto meet a wide variety of application requirements.

The controller can operate in the PID control mode for both heating and cooling, with on-demand Auto-Tune, which will establish the tuning constants. The PID tuning constants maybe fine-tuned by the operator at any time and thenlocked out from further modification. The controller employs a unique overshoot suppression feature, which allows the quickest response without excessive overshoot. Operation of thecontroller canbetransferredto manual mode, providing the operator with direct control of the output. The controller may also be programmed to operate in the ON/OFF control mode with adjustable hysteresis.

Dual 4-digit displays allow viewing of the process/temperature and setpoint simultaneously. Front panel indicators inform the operator of the controller and output status. The control output and the alarm outputs are field replaceable on select models.

Optional alarm (s) can be configured to activate according to a variety of actions (Absolute HI or LO, Deviation HI or LO,Band INor OUT, and Heater Current Break) with adjustable hysteresis. A standby feature suppresses the alarm during power-up until the process stabilizes outside the alarm region.

Optional Main Linear DC output (10 V and 20 mA) can be used for control or retransmission purposes. Programmable output update time reduces valve or actuator activity. The output range can be scaled independent of theinput range.

Optional Second Linear DC output (10 V or 20 mA) provides an independent process retransmission, while the main Linear DC output is being used for control. The output range can be scaled independent of the input range.

The T48 optional Heater Current Monitor provides a direct readout of process heater current. An alarm can be programmed to signal when the heater has failed. This provides early warning of system failure before product quality is affected.

A Remote Setpoint input (0/4 to 20 mA) allows for cascade control loops, where tighter control quality is required; and allows for remotely driven setpoint signal from computers or other similar equipment. Straightforward end pointscaling with independent filtering and local/remote transfer option expands the controller’s flexibility.

The optional RS485 serial communication interface provides two-way communication between a controller andothercompatibleequipmentsuch as a printer, PLC, HMI, or a host computer. In multipoint applications (up to thirty-two), the address number of each controller on the line can be programmed from 0 to 99. Data from the controller can be interrogated or changed, and alarm output(s) may be reset by sending the proper command code via serial communications. PC software, SFCRM, allows for easy configuration of controller parameters. These settings can be saved to disk for later use or used for multi-controller down loading. On-line help is provided within the software.

The unit is constructed of a lightweight, high impact plastic case with a tinted front panel. Thefront panel meets NEMA 4X/IP65 specificationswhen properly installed. Multiple units can be stacked horizontally or vertically. Modern surface-mount technology, extensive testing, plus high immunity to noise interference makes the controller extremelyreliableinindustrialenvironments.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the manual or on equipment must be observed to ensure personal safety and to prevent damage to either the instrument or equipment connected to it. If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

Do not use the controller to directly command motors, valves, or other actuators not equipped with safeguards. To do so, can be potentially harmful to persons orequipmentin the event of a fault to the unit.An independent and redundant temperature limit indicator with alarm outputs is strongly recommended.

INSTALLATION DESCRIPTION

The controller meets NEMA 4X/IP65 requirements for indoor use to provide awatertightseal in steel panels with a minimum thickness of 0.09 inch, or aluminum panels with a minimumthicknessof 0.12 inch. The units are intended to be mounted into an enclosed panel.It isdesigned so that the units can be stacked horizontally or vertically (see Figure

1). The bezel assembly MUST be in place during installation of the unit.

INSTRUCTIONS:

1. Prepare the panel cutout to the dimensions shown in

Figure 1, Panel Installation.

2. Remove the panel latch from the unit. Discard the

cardboard sleeve.

3. Carefully remove the center section of the panel gasket

and discard. Slidethepanel gasket over the unitfrom the

rear, seating it against the lip at the front of the case.

4. Insert the unit into the panel cutout. While holding the

unit in place, push the panel latch over the rear of the

unit, engaging the tabs of the panel latch in the farthest

forward slot possible.

5. To achieve a proper seal, tighten the panel latch screws

evenly until the unit is snug in the panel, torquing the

screws to approximately 7 in-lbs (79 N-cm). Over

tightening can result in distortion of the panel, and

reduce the effectiveness of the seal.

Note: The installation location of the controller is important.

Be sure to keep it awayfrom heat sources (ovens, furnaces,

etc.), and away from direct contact with caustic vapors,

oils, steam, or any other process byproducts in which

exposure may affect proper operation.

Figure 1, Panel Installation

MULTIPLE UNIT STACKING

The controller is designed for close spacing of multiple units. Units can be stacked either horizontally or vertically. For vertical stacking, install the panel latch with the screws to the sides of the unit. For horizontal stacking, the panel latch screws should be at the top and bottom of the unit. The minimum spacing from center line to center line of units is 1.96" (49.8 mm). This spacing is the same for vertical or horizontal stacking.

Note: When stacking units, provide adequate panel ventilation to ensure that

the maximum operating temperature range is not exceeded.

Figure 2, Multiple Unit Stacking Horizontal Arrangement

Caution: Disconnect power to the unit and to the output

control circuits to eliminate the potential shock hazard when removing the bezel assembly.

UNIT REMOVAL PROCEDURE

To remove a unit from the panel, first loosen the panel latch screws. Insert flat blade screwdrivers between the latch and the case on either side of the unit, so that the latches disengage from the grooves in the case. Push the unit through the panel from the rear.

REMOVING BEZEL ASSEMBLY

The bezel assembly, shown in Figure 31, must be removed from the case to replace the output board. To remove the bezel assembly, insert a flat blade screwdriver into the pry slot on either side of the unit. Twist the screwdriver handle until the unit is ejected enough to allow removal.

Figure 3, Bezel Assembly

Caution: The bezel assembly contains electronic circuits that can be damaged by

static electricity. Before removing the assembly, discharge static charge on your body by touching an earth ground point. It is also important that the bezel assembly be handled only by the bezel itself. Additionally, if it is necessary to handle a circuit board, be certain that hands are free from dirt, oil, etc., to avoid circuit contamination that may lead to malfunction. If it becomes necessary to ship the unit for repairs, place the unit in its case before shipping.

INSTALLING BEZEL ASSEMBLY

To install the bezel assembly, insert the assembly into the case until the bezel is fully seated against the lip of the case. Properly installing the bezel assembly is necessary for watertight sealing.

CONNECTION DESCRIPTION

EMC INSTALLATION GUIDELINES

Although Red Lion Controls Products are designed with a high degree of immunity to Electromagnetic Interference (EMI), proper installation and wiring methods must be followed to ensure compatibility in each application. The type of the electrical noise, source or coupling method into a unit may be different for various installations. Cable length, routing, and shield termination are very important and can mean the difference between a successful or troublesome installation. Listed are some EMI guidelines for a successful installation in an industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly connected

to protective earth.

2. Use shielded cables for all Signal and Control inputs. The shield

connection should be made as short as possible. The connection point for

the shield depends somewhat upon the application. Listed below are the

recommended methods of connecting the shield, in order of their

effectiveness.

a. Connect the shield to earth ground (protective earth) at one end where

the unit is mounted.

b. Connect the shield to earth ground at both ends of the cable, usually

when the noise source frequency is over 1 MHz.

3. Never run Signal or Control cables in the same conduit or raceway with AC

power lines, conductors, feeding motors, solenoids, SCR controls, and

heaters, etc. The cables should be run through metal conduit that is

properly grounded. This is especially useful in applications where cable

runs are long and portable two-way radios are used in close proximity or if

the installation is near a commercial radio transmitter. Also, Signal or

Control cables within an enclosure should be routed as far away as possible

from contactors, control relays, transformers, and other noisy components.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.

5. In extremely high EMI environments, the use of external EMI suppression

devices such as Ferrite Suppression Cores for signal and control cables is

effective. The following EMI suppression devices (or equivalent) are

recommended:

Fair-Rite part number 0443167251 (RLC part number FCOR0000)

Line Filters for input power cables:

Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)

6. To protect relay contacts that control inductive loads and to minimize radiated and conducted noise (EMI), some type of contact protection network is normally installed across the load, the contacts or both. The most effective location is across the load. a. Using a snubber, which is a resistor-capacitor (RC) network or metal

oxide varistor (MOV) across an AC inductive load is very effective at reducing EMI and increasing relay contact life.

b. If a DC inductive load (such as a DC relay coil) is controlled by a

transistor switch, care must be taken not to exceed the breakdown voltage of the transistor when the load is switched. One of the most effective ways is to place a diode across the inductive load. Most RLC products with solid state outputs have internal zener diode protection. However external diode protection at the load is always a good design practice to limit EMI. Although the use of a snubber or varistor could be used. RLC part numbers: Snubber: SNUB0000

Varistor: ILS11500 or ILS23000

7. Care should be taken when connecting input and output devices to the instrument. When a separate input and output common is provided, they should not be mixed. Therefore a sensor common should NOT be connected to an output common. This would cause EMI on the sensitive input common, which could affect the instrument’s operation.

WIRING CONNECTIONS

After the unit has been mechanically mounted, it is ready to be wired. All wiring connections are made to the rear screw terminals. When wiring the unit, use the numberson the label and thoseembossedon the back of the case, to identify the position number with the proper function.

All conductors should meet voltage and current ratings for each terminal. Also cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that power supplied to the unit (AC or DC) be protected by a fuse or circuit breaker. Strip the wire, leaving approximately 1/4" (6 mm) bare wire exposed (stranded wires should be tinned with solder). Insert thewireunder the clamping washer and tightenthe screw until the wire is clamped tightly.

Caution: Unused terminals are NOT to be used as tie points. Damage to the

controller may result if these terminals are used.

SIGNAL WIRING

Thermocouple (T48)

When connecting the thermocouple, be certain that the connections are clean and tight, refer to Figure 4 for terminal connections. If the thermocouple probe cannot be connected directly to the controller, thermocouple wire or thermocouple extension-grade wire must be used to extend the connection points (copper wire does not work). Always refer to the thermocouple manufacturer’s recommendations for mounting, temperature range, shielding, etc. For multi-probe temperature averaging applications, two or more thermocouple probes may be connected to the controller (always use the same type). Paralleling a single thermocouple to more than one controller is not recommended. Generally, the red wire fromthe thermocoupleis negative and connected to the controller’s common.

Figure 4, Thermocouple Connection

RTD (T48)

When connecting the RTD, be certain that the connections are clean and tight, refer to Figure 5 for terminal connections. RTD sensors have a higher degree of accuracy and stability than thermocouple sensors. Most RTD sensors available are the three wire type. The third wire is a sense lead for canceling the effects of lead resistance of the probe. Four wire RTD elements may be used by leaving one of the sense leads disconnected. Two wire RTD sensors may be used in eitherof twoways:

A) Attach the RTD to terminals #8 and #10. Install a copper sense wire of the

same wire gage as the RTD leads. Attach one end of the wire at the probe

and the other end to terminal #9. Complete lead wire compensation is

obtained. This is the preferred method. B) Attach the RTD to terminals #8 and #10. Install a shorting wire between

terminals #9 and #10, as shown in Figure 5, RTD Connection. A

temperature offset error of 2.5°C/ohm of lead resistance exists. The error

may be compensated by programming a temperature offset.

Note: With extended cable runs, be sure the lead resistance is less than 15

ohms/lead. For thermocouple or RTD runs longer than 100 feet, convert the

signal to acurrent near the temperature probe.Current or 20 mA loopsignals

are less susceptible to noise and signal loss than long thermocouple or RTD

runs. The RLC ITMA and IRMA DIN rail modules are designed for these

applications. By converting the temperature signal, the P48 can be used in

place of a T48.

Signal (P48)

When connecting signal leads, be certain that the connections are clean and tight. For voltage signals, use terminal #8 for common and terminal #9 for signal. For current signals, use terminal #8 for common and terminal #10 for signal. These connections are shown in Figure 6. Multicontroller applications using the same signal source are possible, by connecting current signals in series, and voltage signals in parallel.

Figure 6, P48 Signal Connection

CONTROL AND ALARM OUTPUTS

For T48 heating, cooling, and alarms, there are up to two types of ON/OFF outputs. These outputs can be relay, or logic for control or alarm purposes. Relay outputs can switch user applied AC or DC voltages. Logic/SSR drive outputs supply power to external SSR power units. One Logic/SSR Drive output can control up to four SSR power units at one time. The P48 is only available with relay outputs. Terminal numbers for the outputs and output types vary from model to model. Refer to the Rear Terminal Assignment Tables or the label on the controller for the terminal numbers corresponding to the model being wired.

Relay Connections

To prolong contact life and suppress electrical noise interference due to the switching of inductive loads, it is good installation practice to install a snubber across the contactor. Follow the manufacturer’s instructions for installation.

Note: Snubber leakage current can cause some electromechanical devices to be

held ON.

POWER WIRING

AC Power

Primary AC power is connected to terminals #11 and #12, labeled AC. To reduce the chance of noise spikes entering the AC line and affecting the controller, an AC feed separate from that of the load should be used to power the controller. Be certain that the AC power to the controller is relatively “clean” and within the variation limit. Connecting power from heavily loaded circuits or circuits that also power loads that cycle on and off, (contacts, relays, motors, etc.) should be avoided.

DC Power

DC power (18 to 36 VDC) is connected to terminals #11 and #12 labeled

DC+ and DC- respectively.

CAUTION: Observe proper polarity when connecting DC voltages.

Damage to the unit may occur if polarity is reversed.

Relay Outputs:

Type: Form-A Rating: 3 Amps @ 250 VAC or 30 VDC (resistive load). Life Expectancy: 100,000 cycles at maximum load rating. (Decreasing

load and/or increasing cycle time, increases life expectancy).

HEATER CURRENT MONITOR WIRING (T48 ONLY)

Models with the Heater Current Monitor option have two input terminals to

receive the output directly from a 100 mA current transformer.

Caution: Never connect a current transformer witha ratingother than 100 mA.

These terminals are labeled #13 and #14 “2nd Input Option”. There is no

polarity observation for these inputs.This input is only for single phase heaters.

REMOTE SETPOINT WIRING

Models with the Remote Setpoint option have two input terminals to receive a 0 to 20 mA signal.Connect the Remote Setpoint signal to terminals labeled #13 (+) and #14 (-), “2nd Input Option”. The common of this input is isolated from input common, but is not isolated from the Linear DC output commons. For proper operation, keep this common isolated from all other controller commons.

MAIN LINEAR DC OUTPUT WIRING

Models with the Linear DC output option provide either a linear 10 V or a linear 20 mA signal. The output range is selected by jumpers on the output board. (See Linear DC Analog Output Jumper Selection, page 12). The terminals are #1 (-) and #2 (+). The common of this output is isolated from input common, but is notisolated from other commons. For proper operation, keep this common isolated from all other controller commons.

SECOND LINEAR DC OUTPUT WIRING

Models with the Second Linear DC output option provide a conditioned and scaledretransmitted signal output.The terminals are #13 (+) and #14 (-). The common of this output is isolated from the input common, but not from the other commons. For proper operation, keepthis common isolated from all other controller commons.

USER INPUT WIRING

The use of shielded cable is recommended. Follow the EMC installation guidelines for shield connection.

Terminal #6 is the User Input, which is programmable for a variety of functions. Any form of mechanical switch may be connected to terminal #6 (USER INPUT) and terminal #8 (COMM.). Sinking opencollector logic with less than 0.7 V saturation and off-state leakage currentof less than 1 µAmay also be used.

SERIAL CONNECTIONS TO A HOST TERMINAL

Six controllers are used to monitor and control parts packaging machines in a plant. The controllers are located at each machine in the production area of the building. A communication line is run toanindustrialcomputerlocated in the production office.

Each controller is programmed for a different address and all are programmed for the same baud rate and parity as the computer (ex. 9600 baud, parity even). An application program is written by the user to send and receive data from the units using the proper commands.

Figure 10, Connecting to a Host Terminal

LINEAR DC ANALOG OUTPUT JUMPER SELECTION

(Main & Second)

The Linear Analog DC Output ranges are selectable for either voltage (0-10 V) or current (0/4-20 mA). The main set of jumpers must correspond with the configuration in Linear Output Range (ANAS) in the Output Parameter Module (2-OP). The optional secondary set of jumpers must correspond with the configuration in Second LinearDC OutputRange(A2tP) in the Second Linear DC Analog Output Module (8-A2). The jumpers are accessible from the rear after removing the controller from the case. Dashed lines show factory setting of 20 mA.

FRONT PANEL DESCRIPTION

The front panel bezel material is flame and scratch resistant, tinted plastic that meets NEMA 4X/IP65 requirements, when properly installed. Continuous exposure to direct sunlight may accelerate the aging process of the bezel. The bezel should be cleaned onlywith a soft cloth and neutral soap product. Do NOT use solvents. There are two 4-digit LED displays, a red upper Main Display and a lower green Secondary Display.

There are up to six annunciators, with red backlighting, that illuminate to inform the operator of the controller and output status. See Figure 12, Front Panel, for a description of the annunciators.

Four front panel buttons are used to access different modes and parameters. The following is a description of each button.

Do NOT use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the

keypad of this unit.

BUTTON FUNCTIONS

D - In the Normal Display Mode, the

Display (D) button is used to

select one of the operational

parameters in the secondary

display. In other modes, pressing

the D button causesthe controller

to exit (escape) directly to the

Normal Display Mode. P - The Parameter (P) button is used

to access programming, enter the

change, and scroll through the

available parameters in any mode. UP, DN - In the Normal Display

Mode, the Up/Down (L/ M)

buttons can be used to directly

modify the setpoint value or

% output power (manual control

only), when viewed in the

secondary display.

INITIAL CONFIGURATION START-UP

CONTROLLER POWER-UP

Upon applying power, the controller delays input indication and control action for five seconds toperform several self-diagnostic tests and to display basic controller information. Initially, the controller illuminates both displays and all annunciators to verify that all display elements are functioning. The controller then displays the programmed input sensor type in the main (top) display and the revisionnumber ofthecontroller’soperating system software in the secondary (bottom) display. The controller checks for correct internal operation and displays an error message (E-xx) if an internal fault is detected. (See Troubleshooting, page 73, for further information).

Upon completion of this sequence, the controller begins displaying the input value and updating the outputs based upon the control calculation.

PARAMETER CONFIGURATION OVERVIEW

The controller is programmed with certain parameter settings from the factory. Factory settings are listed in parentheses in the various Configuration of Parameters tables. In many cases, these settings must be changed to the particulars of the application before proper operation can be started.

The controller is typically in the Normal Display Mode. When changes to parameter configurations are needed,the P button is pressed. From the factory, the controller will enter directly into the Unprotected Parameter Mode. Continue to presstheP button until CnFP appearsin the bottom display. At this time, press the Uparrowbutton and 1-In will appearin the bottom display. This will be the Configuration Parameter Mode. This programming flow is shown in the Front Panel Programming Chart. (If at any time during front panel programming the D button is pressed, the controller will return to the Normal Display Mode and the programming can be started over.)

In the Configuration Parameter Mode, the Up or Down arrow buttons can be pressed to move to the desired Parameter Module. The P button is then pressed to enter into that module. The main (top) display will be theparameter and the secondary (bottom) display will be the parameter value. The Up or Down arrow buttonsare used to change the desired parameter value andthe P button enters the new value and moves to the next parameter.

The Setpoint value (lower display) is changed with the Up or Down arrow buttons when it is selected in the Normal Display Mode.

PARAMETER CONFIGURATION BASIC START-UP

For basic start-up, it is important to verify or change Input Parameter Module (1-IN) parameters tYPE and SCAL, and Output Parameter Module (2-OP) parameter OPAC. For alarm and heat/cool set-up, it is important to verify or change Alarms Parameter Module (4-AL) parameters ACt1, AL-1, ACt2 and AL-2.

If the above Input Parameters or the input wiring connections are not correct, then themain(top) display may display anerror message or incorrect value. Verify the input programming and wiring. (If incorrect display continues refer to Troubleshooting, page 73.) All other parameter configurations are important but will notpreventthe controller from showing a correct display.

PARAMETER CONFIGURATION FOR SERIAL START-UP

The parameter settings can be changed by the front panel buttons or by serial communications using PC Windows based SFCRM software. The controller must have optional RS485 communications. An RS485 to RS232 converter is available from Red Lion Controls for RS232 interfaces. For serial communications set-up, it is important to checkserialwiring and verify or change Serial Parameter Module (6-SC) parameters bAUd, ConF,s and Addr. (See Serial Communications Interface, page 58, for more details.)

CONTROL START-UP

After verifying proper programming and system start-up, a controlling method needs to be configured. For Manual Control or open loop, where the control does not work from the setpoint or process feedback, see Manual Control, page 47. For On / Off Control, set Proportional Band Prop to 0.0% and see On / Off Control, page 48. The controller comes with factory setting for PID Control. However, for optimum PID Control, several options exist for configuring Proportional Band, Integral Time, and Derivative Time parameters for specific applications.

a. Use controller’s built-in Auto-Tune feature (See Auto-Tune For PID

Control, page 51).

b. Use a manual tuning technique (See Manual Tuning For PID Control,

page 56). c. Use a third party tuning software package. d. Use values based oncontrolloop experience, calculated values or values

from a similar process or previous controller.

UNPROTECTED PARAMETER MODE

The Unprotected Parameter Mode is accessed by pressing the P button from the Normal Display Mode with Program Disable inactive. While in this mode, the operator has access to the most commonly modified controller parameters by pressing the P button. The temperature or scaled process value is displayed in the main (top) display.The parameter display will appear with the corresponding range and units in the secondary (bottom) display.

To modify values, use the Up or Down arrows while the parameter is displayed. The controller responds to the new values immediately, however, the change is not committed to non-volatile memory until the controller is returned to the Normal Display Mode. If power loss occurred before returning to the Normal Display Mode, the new values must be entered again.

To gain access to the Configuration Parameter Modules, continueto CnFP and press the Up arrow. These modules allow access to the fundamental set-up parameters of the controller. When the program list has been scrolled through, or the D button is pressed, the controller displays “End” and returns to the normal display mode. The unit automatically returns to the Normal Display Mode if no action is taken.

HIDDEN FUNCTION MODE

The Hidden Function Mode is only accessible from the Normal Display Mode by pressing and holding the P button for three seconds. These functions must first be unlocked in Configuration Module 3-LC. Factory settings for these parameters is lock. In this mode, these controller functions can be performed.

buttons are used to select the operation. Pressing the P button while the function is displayed executes thefunction,and returns the unit to the Normal Display Mode. Pressing the D button exits this mode with no action taken. The unit automatically returns to the Normal Display Mode if no action is taken within a few seconds.

CONFIGURATION PARAMETER MODE

The Configuration Parameter Mode is accessed by pressing the Up button from CnFP in the Unprotected Parameter Mode. While in this mode, the various Configuration Modules can bedisplayed by pressing the Upor Down buttons. The process value (after initial setup) will be displayed in the main (top) display. The Configuration Module will appear alternating with CnFP in the secondary (bottom) display.

To access a Configuration Module, press the P button when the desired Configuration Module is displayed. The parameters of that Configuration Module can be accessed by pressing the P button. (The module’s parameters are listed in the appropriate Configuration Module table in this section with configuration parameter explanations beginning on page 31.) To modify ranges and units, use the Up or Down arrows while the parameter is displayed. The controller responds to the new values after the P button is pressed, however, the change is not committed to permanent memory until the controller is returned to the Normal Display Mode. If power loss occurred before returning to theNormal DisplayMode, the new values must be entered again. Whenever the D button is pressed, End will momentarily appear and the controller will return to the Normal Display Mode. At the end of each module, the controller will go to CnFP no. Pressing the Up or Down arrows will continue in ConfigurationParameterMode and pressing the Pwill return to the Normal Display Mode.

Unless specified, the parameters, ranges, units and factory settings are the same for T48 and P48 controllers. Parameters that are model number or program dependent will only be displayed when the appropriate options are installed or programmed. Some parameters are accessible but may not be applicable for the chosen output control mode type.

CONFIGURATION PARAMETER EXPLANATIONS

Input Parameter Module (1- IN) T48 Models

The controller has several input set-up parameters that must be

programmed prior to setting any other controller parameters.

Input Type (tYPE)

Select from the list of various thermocouple and RTD sensors. The following is a list of the possible sensors:

tc-t Type T TC tc-E Type E TC tc-J Type J TC tc-k Type K TC tc-r Type R TC tc-S Type S TC tc-b Type B TC tc-N Type N TC LIN Linear mV display r385 385 curve RTD r392 392 curve RTD rLIN Linear ohms display

Temperature Scale (SCAL)

Select either degrees Fahrenheit (F) or degrees Celsius (C).

If changed, be sure to check all parameters.

Temperature Resolution (dCPt)

Select either 1 or 0.1 degree resolution.

If changed, be sure to check all parameters.

Digital Input Filtering and Display Update Rate (FLtr)

step response time is minimal. If the signal is varying too greatly due to measurement noise, increase the filter value. Additionally, with large derivative times, control action may be too unstable for accurate control. Increase the filter value. Conversely, if the fastest controller response is desired, decrease the filter value.

The Auto-tune procedure sets the filter value appropriate to the process characteristics. Also see Output Power Dampening parameter (OPdP), page 36, for filtering the output.

Fltr- 0 to 4

0 = least input filtering 3 = most input filtering 4 = most input filtering and slower (500 msec) display update rate

(outputs update at 100 msec rate)

Input Sensor Correction Constant (SHFt)

If the controller temperature disagrees with a reference temperature instrument or if the temperature sensor has a known calibration, the controller temperature can be compensated by a correction offset (SHFt).

SHFt - -999 to 9999 The following equation expresses the relationship: Desired Display Temp = (Controller Temp) + SHFt

Example 1: The controller reads 293°F whilea referenceinstrumentindicates

300°F. A SHFt value of +7°F corrects the controller indication to match the reference.

Setpoint Limit Values (SPLO & SPHI)

The controller has programmable high and low setpoint limit values to

restrict the setting range of the setpoint. Set the limit values so that the temperature setpoint value cannot be set outside the safe operating area of the process.

SPLO - -999 to 9999

SPHI - -999 to 9999

-31-

Setpoint Ramp Rate (SPrP)

The setpoint can be programmed to ramp independent of the controller’s display resolution. Thesetpoint ramp feature canreduce thermal shock to the process, reduce temperature overshoot on start-up or setpoint changes, or ramp the process at a controlled rate.

SPrP - 0.0 to 999.9 degrees/minute

A ramp value of zero disables setpoint ramping, allowing the controller to stabilize as fast as possible to the new setpoint. If the user input is programmed for setpoint ramp, it affects the enabling and disabling of setpoint ramping. Setpoint ramping is initiated on power-up or when the setpoint value is changed. Active setpoint ramping is indicated by the left most decimal point flashing in the main display.

Figure 13, Setpoint Ramp Rate

Once the ramping setpoint reaches the target setpoint, the setpoint ramp rate disengages until the setpoint is changed again. If the ramp value is changed during ramping, the new ramp rate takes effect. If the setpoint is ramping prior to invoking Auto-Tune, the ramping is suspended during Auto-Tune and then resumed afterward using the current temperature as a starting value. Deviation and band alarms are relative to the target setpoint, not the ramping setpoint.

The Remote Setpoint input is also controlled by the setpoint ramp feature. In situations where the remote setpoint must be rate controlled, this parameter can be used to slowly increment (or decrement) the signal to its final value. The target value, not the instantaneous ramp value, is displayed. Setpoint ramp indication is disabled during remote setpoint ramping.

Note: Depending on the thermal characteristics of the process, the process

temperature may not track the programmed setpoint rate.

User Input (InPt)

The user input may be programmed to perform a variety of controller functions. The input must be in its active state for 120 msec minimum to perform the function. A function is performed when the User Input, (Terminal 6) is pulled low to common (Terminal 8).

Note: Do not tie the commons of multiple units to a single switch. Use either a

multiple pole switch for ganged operation or a single switch for each unit.

Note: “Low Level” is switch closed.

“High Level” is switch open.

PLOC - Program Lock. A low level enables the program disable function

which places the unit in the Protected Parameter Mode.

ILOC - Integral Action Lock. A low level disables the integral action of the

PID computation. A high level resumes the integral action.

trnF - Auto/Manual Transfer. A negative transition places the unit in the

manual (user) mode and a positive transition places the unit in the

automatic operating mode. The output is “bumpless” when transferring to

either operating mode. SPrP - Setpoint Ramp. A low level terminates setpoint ramping and the

controller operates at the target setpoint. Terminating setpoint ramping is

the same as setting the ramp rate to zero (SPrP = 0.0). A high level enables

the programmed setpoint ramp rate. ALrS - Alarm Reset. On models with alarms, a low level resets any active

alarm(s) to their inactive state as long as the user input is low. SP2 - Setpoint 1/ Setpoint 2 Select. On models with Second Setpoint, a low

level selects setpoint 2. A high level selects setpoint 1.

SPSL or RSP - Local/Remote Select. On models with Secondary Analog

Input, a negative transition engages Remote Setpoint operation and a positive transition engagesLocal Setpoint operation. The response of the controller to the setpoint transfer is set by the setpoint transfer parameter “trnF”, under “7-rS” or “7-n2” module.

Prnt - Print Request. On models with Serial Communications, a low level

transmits the print option selected in the Serial Communications Module (6-SC). If the user input is held low,after theprintingiscomplete,another request is issued.

Input Parameter Module (1- In) P48 models

The controller has several input set-up parameters that must be

programmed prior to setting any other controller parameters.

Input Type (tYPE)

Select the signal input type: Voltage(VOLt), or Current (Curr). The signal

input terminal for voltage is #9 and for current is #10. Common is #8.

Decimal Point Position (dCPt)

Select the desired decimal point position for the scaled display. The selected decimal point position appears in the following parameters; rnd, dSP1, dSP2, SPLO, SPHI, SP, AL1, AL2, db-2, AHYS, and CHYS.

0.0

0.00

0.000

Rounding Increment ( rnd)

Rounding values other than “1” causes the scaled number to ‘round’to the nearest rounding increment selected (i.e.. rounding of ‘5’ causes ‘122’ to round to ‘120’ and ‘123’toround to ‘125’). If the process isinherentlyjittery, the display value may be rounded to a higher valuethan “1”.Ifthe range of the process exceeds the required resolution, (ex. 0-1000 PSI, but only 10 PSI resolution required), a rounding increment of 10 will effectively make the display more stable.

This programming step is usually used in conjunction with programmable digital filtering to helpstabilizedisplay readings. (If display stability appears to be a problem and the sacrifice in display resolution is unacceptable, program higher levels of digital filtering or increase the level of process dampening.) Rounding increments of 10, 20, 50, and 100 may also be used to add “dummy zeroes” to the scaled readings, as desired.

1 2 5 10 20 50 100

The rounding increment is for the controller’s display only and does not affect (improve or degrade) the control accuracy of the unit.

Digital Input Filtering and Display Update Rate (FLtr)

Select the relative degree ofinputsignal filtering and display update rate. The filter is an adaptive digital filter that discriminates between measurement noise and actual process changes. Therefore,the influence on step response time is minimal. If the signal is varying too greatly due to measurement noise, increase the filter value. Additionally, with large derivative times, control action may be too unstable for accurate control. Increase the filter value. Conversely, if the fastest controller response is desired, decrease the filter value.

The Auto-tune procedure sets the filter value appropriate to the process characteristics. See Output Power Dampening parameter (OPdP), page 36, for filtering the output.

Fltr- 0 to 4

0 = least input filtering 3 = most input filtering 4 = most input filtering and slower (2/sec) display update rate

(outputs update at 10/sec rate)

Scaling Points

Prior to installing and operating the controller, it may be necessary to change the scaling to suit the display units particular to the application. Although the unit has been programmed at the factory, the scaling will generally have to be changed.

The controller is unique in that two differentscaling methodsare available. The two scalingprocedures are similar in that the operator keys inthe display values and either keys in or applies a signal value that corresponds to those scaling points. The location of the scaling points should be near the process end limits, for the best possible accuracy.

Once these values are programmed (coordinates on a graph), the indicator calculates the slope and intercept of the signal/display graph automatically. No span/zero interaction occurs, making scaling a one-pass exercise.

Figure 14, Scaling Points

-33-

Before programming the indicator, it is advised to organize all thedata for

the programming steps to avoid possible confusion.

To scale the indicator, two signal values and two display values that correspond to the signal values must be known. These four values are used to complete the scaling operation. An example is listed below:

Scaling Point #1 Scaling Point #2

0.0% @ 4.00 mA & 100.0% @ 20.00 mA

Reverse acting indication can be accomplished by eitherreversing the two signal points or the display value points, but not both. If both are reversed, then forward (normal) acting indication will occur. In either case, do not reverse the input wires to correct the action.

Display Values (dSP1 & dSP2)

Key-in the display value for scaling point one and scaling point two.

dSP1 -999 to 9999 (Ex. 0.0%) dSP2 -999 to 9999 (Ex. 100.0%)

Signal Input Values (INP1 & INP2)

The signal input value can either be keyed in via the front panel buttons or an input signalcan be applied to theappropriate signal input terminals. When entering the signal input parameter, the unit is in the key-in mode.

Key-in Method

Key-in the signal value for scaling point one and scaling point two.

INP1 -999 to 9999 (Ex. 0.00 VDC or 4.00 mA DC) INP2 -999 to 9999 (Ex. 10.00 VDC or 20.00 mA DC)

Signal Input Method

To change to the apply signal method press the D button. Front panel annunciators %P andDV will flash, and thedisplay indicates the signalvalue applied to the input terminals. The unit canbe toggledto the key-in method by pressing the D button again.

Signal Range Display Range

4.00 to 20.0 mA DC 0.00 to 20.00

0.00 to 10.00 VDC 0.00 to 10.00

When the desired value is indicated on the display, press the P button to store the value and advance to the next parameter.

Setpoint Limit Values (SPLO & SPHI)

The controller has programmable high and low setpoint limit values to restrict the setting range of the setpoint. Set the limit values so that the setpoint value cannotbe set outside thesafe operating area ofthe process. On models equipped with Second Analog Input, configured as a Remote Setpoint, the Remote Setpoint reading is also restricted to these limits.

SPLO - -999 to 9999

SPHI - -999 to 9999

Setpoint Ramp Rate (SPrP)

The setpoint can be programmed to ramp independent of the controller’s decimal point position and rounding increment. The setpoint ramp rate can reduce sudden shock to the process, reduce overshoot on start-up or setpoint changes, or ramp the process at a controlled rate.

SPrP - 1 to 9999 units/minute

Note: Defined here, a unit is the LSD of the display, regardless of decimal point

position.

A ramp value of zero disablessetpoint ramping.Ifthe optional user input is programmed for setpoint ramp, it affects the enabling and disabling of setpoint ramping. Setpoint ramping is initiated on power-up or when the setpoint value is changed. Active Setpoint Ramping is indicated by the left most decimal point flashing in the main display.

Figure 15, Setpoint Ramp Rate

-34-

Once the ramping setpoint reaches the target setpoint, the setpoint ramp rate disengages until the setpoint is changed again. If the ramp value is changed during ramping, the new ramp rate takes effect. If the setpoint is ramping prior to invoking Auto-Tune, the ramping is suspended during Auto-Tune and thenresumed afterward using thecurrent display as astarting value. Deviation and band alarms are relative to the target setpoint, not the ramping setpoint.

Note: Depending on the ramp rate relative to the process dynamics, the actual

scaled process value may not track the ramping setpoint value.

User Input (InPt)

Note: Do not tie the commons of multiple units to a single switch. Use either a

multiple pole switch for ganged operation or a single switch for each unit.

Note: “Low Level” is switch closed.

“High Level” is switch open.

PLOC - Program Lock. A low level enables the program disable function

which places the unit in the Protected Parameter Mode.

ILOC - Integral Action Lock. A low level disables the integral action of the

PID computation. A high level resumes the integral action.

trnF - Auto/Manual Transfer. A negative transition places the unit in the

manual (user) mode and a positive transition places the unit in the

automatic operating mode. The output is “bumpless” when transferring to

either operating mode. SPrP - Setpoint Ramp. A low level terminates setpoint ramping and the

controller operates at the target setpoint. Terminating setpoint ramping is

the same as setting the ramp rate to zero (SPrP = 0.0). A high level enables

the programmed setpoint ramp rate.

ALrS - Alarm Reset. On models with alarms, a low level resets any active

alarm(s) to their inactive state as long as the user input is low.

SP2 - Setpoint 1/ Setpoint 2 Select. On models with Second Setpoint, a low

level selects setpoint 2. A high level selects setpoint 1.

SPSL or RSP - Local/Remote Select. On models with Secondary Analog

PrNt - Print Request. On models with Serial Communications, a low level

transmits the print option selected in the Serial Communications Module (6-SC). If the user input is held low,after theprintingiscomplete,another request is issued.

Output Parameter Module (2-OP)

The controller hasparameters that affect how the main control output (O1) and Main Linear DC output control signal responds to temperature changes and sensor failures.

Time Proportioning Cycle Time (CYCt)

The selection ofcycletimedepends on the time constant of theprocess and the type of output used.

CYCt - 0 to 250 seconds

For best control, a cycle time equal to 1/10 of the process time constant, or less is recommended; longer cycle times could degrade temperature control, and shorter cycle timesprovidelittle benefit at the expenseof shortened relay life. When using a Logic/SSR drive output with the SSR Power Unit, a relatively short cycle time may be selected.

A setting of zero keeps the main control output and front panel indicator off. This is useful if using the linear DC output signal for control. On some models, output (O1) can be configured as an alarm output ACt1 under Module “4-AL”.

Output Control Action (OPAC)

For heat and cool applications, the main output (O1) is normally used for heating (reverse acting) and the optional cooling output (O2) is normally used for cooling (direct acting).

OPAC - rEv (Reverse acting)

drct (Direct acting)

If O2 (cooling) is not used, then the action can be reverse or direct acting. When used for control output, the Main Linear DC output operation is affected by this parameter.

Output Power Limits (OPLO & OPHI)

Enter the safe output power limits for the process. These parameters may also be used to limit the minimum and maximum controller power due to process disturbances or setpoint changes, to reduce overshoots by limiting the process approach level.

OPLO & OPHI - 0 to 100%

If the cooling output is selected, the limits range from:

OPLO & OPHI - -100 to 100%

With Alarm 2 selected for cooling, the Lower Limit can be set to less than 0% to limit maximum cooling or set to greater than 0% to limit minimum heating. Set the High Limit to less than 0% to limit minimum cooling or greater than 0% to limit maximum heating. When controlling power in the manual control mode, the output power limits do not take effect.

Sensor Fail Power Level (OPFL) T48 only

If a failedsensor is detected, thecontrol output(s) default toa preset power output.

OPFL - 0% (O1 output full “off”) to 100% (O1 output full “on”)

If Alarm 2 is selected for cooling , the range is extended from:

OPFL - -100% to +100%

At 0% both outputs are off, at 100%O1 ison and O2 is off, and at -100% O2 is on and O1is off. The alarm outputs are up-scale drive(+9999)with an open sensor, and down-scale drive (-9999) with a shorted sensor (RTD only), independent of this setting. Manual Control overrides OPFL.

Output Power Dampening Filtering Time (OPdP)

The output power calculated by the PID controller can be dampened (filtered) to reduce the controller output activity. Those processes with high gain and/or derivative times, or those processes with a relatively high noise content, can benefit from the dampening action.

OPdP - 0 to 250 seconds

The dampening parameter is expressed as a time constant in seconds. Increasing the value increases the dampening or filtering effect. A value of zero disablesoutput power dampening. The amount of dampening to be used depends primarily on theresponse time of the processand the amount of final actuator activity desired. Generally, dampening times in the range of 1/20 to 1/50 of the controller’s integral time (or process time constant) prove to be effective. Dampening times longer than these may cause controller instability due to the added lag effect of too much filtering.

In the case where a relatively high dampening time is desired, the controller’s proportional band may be increased to restore an adequate stability margin. The Auto-tune procedure of the controller sets the dampening value appropriate to the characteristics of the process.

-36-

ON/OFF Control Hysteresis (CHYS)

The controller can be placed in the ON/OFF control mode by setting the proportional band to 0.0%. The control hysteresis value affects only the control outputs. Alarms have a separate hysteresis setting. See ON/OFF Control, page 48, for more details.

CHYS - 1 to 250

The hysteresis band should be set to a minimum value to eliminate output chatter at the setpoint. Generally, 2 to 5 is sufficient for this purpose. Set the hysteresis band to factory setting prior to invoking Auto-Tune. After Auto-Tune, the hysteresis band has no effect on PID Control.

Auto-Tune Code (tcod)

Prior to invoking Auto-Tune, the Auto-Tune code should be set to achieve the desired dampening level under PID Control. After Auto-Tune is complete, changes to “tcod”parameter have no effect until Auto-Tune is restarted. When set to 0, this yields the fastest process response with possible overshoot. A setting of 2 yields the slowest response with the least amount of overshoot. Dampening codes of 0 or 1 are recommended for most thermal processes.

Main Linear DC Output Range (ANtP) (Optional)

Select the type of output range:

0-10 = 0 to 10 V 0-20 = 0 to 20 mA 4-20 = 4 to 20 mA

The linear DCoutput range jumper must be setto match the range selected. See Linear DC Output Jumper Selection, page 12. The linear DC output can be re-calibrated to provide up to 5% of over range operation. See Main or Second Linear DC Analog Output Calibration, page 71.

Main Linear DC Output Source (ANAS) (Optional)

The output can be programmed to transmit one of the below variables:

OP - Output Power % control INP - Temperature retransmission SP - Setpoint (local or remote) retransmission

For Linear DC Output control, the main output (O1) can be disabled by setting the Cycle Time (CYCt) to 0 in Output Parameter 2-OP or configuring it as an alarm in Alarm 1 Action (ACt1) in Alarm Parameter 4-AL. For heat/cool with 4 to 20mA controlapplications,theheat (0 to 100%) will be 12 to 20 mA and the cool(-100 to0%) will be 4 to 12 mA. Notice that 0% (noheat or cool) is 12 mA.

Main Linear DC Update Time (ANUt) (Optional)

To reduce excess valve actuator, or pen recorder activity, the update time of the linear output can beset over the rangeof 0.1 to 250 seconds. A value of 0 seconds results in an update time of 0.1 second.

Main Linear DC Output Scaling Points (ANLO, ANHl) (Optional)

The output is scaled based on the Output Source (ANAS) display by use of low and high scaling parameters. Reverse acting output is possible by reversing the scaling points.

Figure 16, Auto-Tune Code

ANLO – Display value that corresponds to 0 V, 0 mA, or 4 mA as

selected.

ANHI – Display value that corresponds to 10 V or 20 mA as

selected.

Lockouts Parameter Module (3-LC)

The controller can be programmed to limit operator access to various parameters, control modes, and display contents. The configuration of the lockouts is grouped into three sections: Lower Display Lockouts, Protected Mode Lockouts and Hidden Mode Lockouts.

Lower Display Lockouts (SP, OP, dEv, Hcur, UdSP and bdSP)

The contents of the secondary display can be changed in the Normal Display Mode by successively pressing the D button. This action scrolls through the possible display parameters, when enabled. If all parameters are settolock“LOC”,pressDtoblankthedisplay.

The parameters can be set for one of the following:

LOC (Lockout) – Prevents the parameter from appearing in the

rEd (Read only) – Parameter appears, but cannot be modified. Ent (Entry) – Parameter appears and can be modified.

The lower display content possibilities are:

SP – Setpoint Value OP – % Output Power dEv – Setpoint Deviation UdSP – Temperature Units (T48) bdSP – Blank Display (P48) Hcur – Heater Current Readout*

* Models equipped with Heater Current Option replace “DEv” (Deviation)

readout with “Hcur” (Heater current readout).

Note: If a parameter is active in the lower display and is then subsequently

locked out, press “D” once in theNormal Display Mode to remove it from the

display.

Protected Mode Lockouts (CodE, PId, and AL)

The protected mode is active when program disable is active. The parametersin the protected mode can be set for one of the following modes:

LOC (Lockout) – Prevents the parameter from appearing in the

rEd (Read only) – Parameter appears, but cannot be modified.

secondary display.

protected mode.

Ent (Entry) – Parameter appears and can be modified.

The code number allows access to the unprotected mode. To enter the unprotected mode from the protected mode, the code number entered must match the code number entered here. See Front Panel Program Disable, page 17, for a description of the various program access levels.

CodE – 0 to 250

PId – Permits access to the main PID parameters.

AL – Permits access to the alarm value(s).

Hidden Mode Lockouts (ALrS, SPSL, trnF, and tUNE )

The hidden mode is accessible fromthe Normal Display Modeby pressing and holding the P button for three seconds. The parameters can be set for:

LOC (Lockout) – Prevents the parameter from appearing in the

ENbL (Enable) – Allows operator to perform the selected hidden

hidden mode.

mode function.

The functions available in the hidden mode are accessible independent of the status of program disable.

ALrS – Reset (override) the alarm output(s).

SPSL – SP1/SP2/Remote setpoint selection.

trnF – Select Automatic or Manual operation.

tUNE – Invoke or cancel Auto-Tune.

** Model Number Dependent.

-38-

Alarm Parameter Module (4-AL) (Optional)

The controller may be equipped with one or two optional alarms. On some models alarm output #1 is the same output as main control O1. In this case,the output is either programmedfor the mainoutputcontrol function (O1) or as an alarm function (A1). This is set by alarm #1 action parameter (Act1).

If heat is selected, the remaining Alarm 1 parameters do not appear.

To enable the cooling output of the controller, select CooL for Alarm 2 action (Act2). The controller then utilizes the alarm 2 output as the cooling output (O2). Front panel annunciator A2 illuminates whenever the cooling output is on. See Cooling Output Module (5-O2), page 43, for configuration of the cooling output.

If cooling is selected, the remaining Alarm 2 parameters do not appear.

Alarm Action (Act1, Act2)

Note: When deviation low-acting with positive alarm value (d-LO), deviation

high-acting with negative value (d-HI), or Band inside-acting (b-IN) is

selected for the alarm action, theindicator is “OFF” whenthe alarm output

is “ON”.

Caution: In applications where equipment or material damage, or risk

to personnel due to controller malfunction could occur, an independent and redundant temperature limit indicator with alarm outputs is strongly recommended. The indicators should have input sensors and AC power feeds independent fromthe otherequipment.

The configuration options of the alarm output are model dependent.

break alarm (T48)

Heater Break Alarm

T48 models equipped with the Heater Current Monitor provide an alarm output in the event of a heater or a heater control circuit failure. The alarm is dual mode and activates under either of the following two conditions:

1. Main control output (O1) is on fora minimum of 600 msec and the feedback

heater current is below the alarm value.

2. Main control output (O1) is off for a minimum of 600 msec and the

feedback heater current is above 10% +0.5 amp of the alarm value.

For heater ground faults, the heater power circuit fuse opens. The heater break alarm activates per condition one above. This alarm is only useful for controller output cycle times (CYCt) of 10 seconds or more, due to the minimum on and off times of alarm detection.

The heater break alarm value is usually set in the range of 50% to 80% of the nominal heater current. This usually provides sufficient margin against false alarms that may occur fromline voltage drops and normal heater aging. Set the alarm value after observing the actual heater current readout.

If the alarm is set forlatching operation,the controller delays alarm action an additional 1 second (both on and off alarm detection). This suppresses false alarm outputs in theevent of a briefpower glitch in theheatercircuit. A latched heater break alarm requires manual reset. If the alarm is set for auto reset (non-latching), oncepast the 600 msec minimum dwell time the alarm triggers and releases immediately after the condition that caused the alarm clears.

Alarm Action Figures

The alarm action figures describe the status of the alarm output and the front panel indicator for various over/under temperature conditions. The alarm output wave formis shown with the output in the automatic reset mode.

Note: Select the alarm action with care. In some configurations, the front panel

indicator (LED) might be “OFF” while the output is “ON”.

-40-

-41-

Alarm Reset (rSt1, rSt2)

Each alarm reset action may be independently configured.

LAtC - Latched Auto - Automatic

Latched alarms require operator action to reset the alarm condition. The front panel buttons can be used to reset an alarm when the controller is in the Hidden Function Mode (See page 20). An alarm condition may also be reset via the user input.

Automatic reset alarms are reset by the controller when the alarmcondition clears. Figure 17, Alarm Reset Sequence, depicts the reset actions.

Figure 17, Alarm Reset Sequence

Alarm Standby Delay (Stb1, Stb2)

The alarm(s) may be independently configured to exhibit a power-on, standby delay which suppressesthe alarm output from turning “ON”until the temperature first stabilizes outside the alarm region. After this condition is satisfied, the alarm standby delay is canceledand the alarmtriggersnormally, until the next controller power-on. This feature also works for deviation and band alarms when the setpoint ischanged via keypad. This action suppresses “nuisance” alarms. Figure 18, Alarm Standby Delay Sequence, depicts a typical operation sequence.

Figure 18, Alarm Standby Delay Sequence

Alarm Value (AL-1, AL-2)

The alarm values are either absolute (absolute alarms) or relative to the setpoint value (deviation and band alarms). Anabsolute alarm value is the value that is entered. A relative alarm value is offset from the temperature setpoint value by the amount entered and tracks the setpoint value as it is changed.

AL-1 and AL-2 - -999 to 9999

If the alarm action is set as a Band Alarm, then only a positive value can be entered.

Alarm Hysteresis (AHYS)

The alarm value(s) have a programmable hysteresis band to prevent alarm output chatter near the alarm trigger point. The hysteresis value should be set to eliminate this effect. A value of 2 to 5 is usually sufficient for most applications. A single alarm hysteresis value applies to both alarms. See the Alarm Action Figures, page 40, for the effect of hysteresis on the various alarm types.

AHYS - 1 to 250

-42-

Cooling Parameters Module (5-02) (Optional)

The cooling output (O2) is software selectablewith dualalarmmodels(For the P48, this is referred to as the Second Control Output). This output operates as an independent cooling output for systems that use heating and cooling. To enter the Cooling Output Module, the cooling output of the controller must first be selected in Alarm Module (4-AL). When cooling is selected, alarm 2 is used for the cooling output.

The front panel indicator A2 illuminates when the cooling output (O2) is on. Cooling output power is defined as ranging from -100% (full cooling) to 0% (no cooling, unless a heat-cool band overlap is used). See Output Power Limits in Module 2 for maximum and minimum settings. The same PID values control both heat and cool.

Cooling Output Cycle Time (CYC2)

A value of 0 turns off the cooling output, independent of cooling power demand.

CYC2 - 0 to 250 seconds

Cooling Relative Gain (GAn2)

This parameter defines the gain of the cooling band relative to the heating band. A value of 0.0 places the cooling output into ON/OFF Control mode with the ON/OFF Control Hysteresis (CHYS) in Output Parameter Module (2-OP) becoming the cooling output hysteresis. This may be done independent of the main output control mode (PID or ON/OFF). Relative gain is generally set to balance the effects of cooling to that of heating for best control. Figures 19, 20, & 21, Heat/Cool Operation, illustrate the effect of different gains.

GAN2 - 0.0 to 10.0

Heat and Cool Overlap/Deadband (db-2)

This parameter defines the area in which both heating and cooling are active (negative value) or the deadband area between the bands (positive value). The parameter units are degrees or tenth’s of degrees (depending on system resolution). If a heat/cool overlap is specified, the displayed percent output power is the sum of the heat power (O1) and the cool power (O2).

db-2 - -999 to 9999

When the Cooling Relative Gain is set to zero for ON/OFF Control mode, this parameter should only be set to a positive value or zero. The Heat/Cool Operation Figures illustrate the effects of different deadbands.

Figure 19, Heat/Cool Operation (db=0)

Figure 20, Heat/Cool Operation (db>0)

When using the cooling output, observe the controlled temperature characteristics. If the temperature remains above setpoint with a sluggish return, increase the cooling gain. Similarly, if the temperature drops too

-43-

sharply with an overall saw-tooth pattern,decrease thecooling gain. Alter the heat-cool overlap until a smooth response in the controlled temperature is observed during band transition.

Figure 21, Heat/Cool Operation (db<0)

Serial Communications Module (6-SC) (Optional)

Unless controller serial configurations match those of the host communicating device, front panel serial parameter changing is needed for communication. Baud rate and character frame must be the same as the other communicating device. The controller address is the unique node address for multiple controllers applications. (See Serial Communications Interface, page 58, for further explanations.)

Baud Rate (bAUd)

The available baud rates are:

300, 600, 1200, 2400, 4800, or 9600

Character Frame Format (ConF)

The character frame can be 7O1, 7E1, 7n2, or 8n1..

Controller Address Number (Addr)

Multiple controllers connected on thesameRS485 interface line must each have a different address number. A value of 0 does not require the address specifier command, when communicating with the controller. The address numbers range from 0 to 99.

Abbreviated or Full Transmission (Abrv)

When transmitting data, the controller can be programmed to suppress the address number, mnemonics, units, and some spaces by selecting YES. An example of abbreviated and full transmission are shown below:

NO - 6 SET 123.8F<CR> <LF> Full Transmission YES - 123.8<CR> <LF> Abbreviated Transmission

Print Options (PoPt)

Selecting YES for the print options allows the operator to scroll through the available options using the P button. The up and down arrow keys toggle between “yes” and “no”. “yes” enables the option to be printed when a print function occurs.

INP - Print Input Process Value SEt - Print Setpoint Value OPr - Print % Output Power Value Pbd - Print % Proportional Band Value INt - Print Integral Time Value dEr - Print Derivative Time Value AL1 - Print Alarm 1 Value AL2 - Print Alarm 2 Value dEv - Print Deviation From Setpoint Value OFP - Print % Output Power Offset Value r_P - Print Ramp Rate Crg - Print Relative Gain Value Cdb - Print Deadband Value OSt - Print Output Status rSP - Print Remote Setpoint Reading HCr - Print Heater Current Reading

Remote Setpoint Parameters Module (7-n2 or 7-rS) (Optional)

Configuration of the Remote Setpoint involves scaling the input to the desired setpoint range, selecting filter characteristics, and setting remote/local setpoint transfer response.

Remote Setpoint Display Values (dSP1 and dSP2)

Key-in the display value for Scaling Point 1 and Scaling Point 2.

dSP1 -999 to 9999 (Ex. 0) dSP2 -999 to 9999 (Ex. 500)

Remote Setpoint Signal Input Values (INP1 and INP2)

The signal input value can either be keyed-in via the front panel buttons or an input signal can be applied to the appropriate signal input terminals. Initially, the unit is in the key-in method.

Key-in Method

Key-in the display value for Scaling Point 1 and Scaling Point 2.

INP1 0.00 to 20.00 (Ex. 4.00 mA DC) INP2 0.00 to 20.00 (Ex. 20.00 mA DC)

Signal Input Method

To change to the apply signal input method, press the D button while InP1 or InP2 is displayed. Front panel annunciators %P and DV flash and the display indicates the signal value applied to the input terminals. The controller can be toggledto the key-in method by pressing the D buttonagain. In this case, the previously accepted value is recalled.

When the desired value is indicated on the display, press the P button to store the value and advance to the next parameter.

Remote Setpoint Filtering (Fltr and bANd)

The remote setpoint signals can be filtered with a time constraint from1 to 25 seconds; or the filter can be disabled. The filter is an adaptive, first-order, low pass type. As long as the difference between the current reading and the previous reading is less thanthe filter band value (band), the filter remains in effect. When thedifference exceeds the filter band,the filter disengages until the difference is less than thefilter band value. Thisaction allows quick filter response to large setpoint changes, while retaining filtering action under normal process conditions.

Normally the filter band value is set slightly larger than the noise level of the remote input. The time constant of the filter is set consistent with the amount of filtering desired.Increasedfilter time constant values are effective for smoothing remote setpoint readings. This may be beneficial for cascade operation and other “live” signal applications.

Alternatively, the remote setpointcan be ramped at a controlledvelocity to limit controller response to large setpoint changes.

Remote/Local Setpoint Transfer Options (trnF)

When switching between Local or Remote Setpoint, the response of the controller can be programmed in a variety of ways.

These responses apply to changes in setpoint mode from the controller’s front panel and User Input. The table summarizes the responses for Setpoint transfer operations:

SPtr Parameter Local to Remote Remote to Local

nor – Output may bump. Output may bump

Auto – No output bump. Process

error eliminated at rate of integral action

trAC – Output may bump. Local setpoint assumes

No output bump. Process error eliminated at rate of integral action

value of Remote setpoint (tracks). No Output bump.

Note: In situations where an output bump may occur,the setpoint ramp function

(SPrP) can be used to reduce or eliminate bumping when switching between

setpoints.

Heater Current Monitor Module (7-N2 or 7-HC) (Optional)

Enter the full scale rating of the current transformers used with the T48 controllers. This scales the Heater Current Monitor of the controller to indicate directly in amperes of heater current.

Hcur - 0.0 to 999.9 amperes

Alternatively, the Heater Current Monitor may be scaled to indicate in percent of nominal heater current (0.0 to 100.0%). This may be useful in applications employing severalcontrollers, each withnominal heater current readings that are differentfromeach other. In this case,eachcontroller can be scaled to indicate the same reading (100.0%), independent of each controller’s actual heater current. For example, if using a 50 ampere current transformer and the actual maximum heater current is 38 amperes,the Heater Current Monitor scaling value is:

50.0 Amperes

Hcur

This scaling value results in a Heater Current Monitor indication of

100.0% at an actual heater current of 38 amperes.

Second Linear DC Analog Output Module (8-A2) (Optional)

The Second Linear DC Analog Output provides retransmission of the

conditioned and scaled input signal independent of the Main Linear DC Output.

Second Linear DC Output Range (A2tP)

Select the type of output range:

0-10 = 0 to 10 V 0-20 = 0 to 20 mA 0-40 = 4 to 20 mA

The linear DCoutput range jumper must be setto match the range selected. See Linear DC Output Jumper Selection, page 12. The linear DC output can be re-calibrated to provide up to 5% of over range operation. See Linear DC Output Calibration, page 71, for more details.

Second Linear DC Output Scaling Points (A2LO, A2Hl)

The output can be scaled based on the controller’s input display by use of low and high scaling parameters. Reverse acting output is possible by reversing the scaling points.

Factory Service Operations Module (9-FS)

The Factory Service Operations include: controller calibration, and reset programming to factory configuration setting. Access to each operation is protected by anaccess code number. Entering code 66 restores allparameters to factory settings, the unit indicates the operation after the P button is pressed, by displaying “rSEt” in the lower display momentarily.

Caution: Entering code 77,twice in succession, erases the controller calibration

values and defaults the values to nominal settings. Reading errors of

may result. Do not perform this operation unless the controller has lost

calibration. Loss of calibration is signaled by an “E-CL” error flag at

power-up. To clear this flag, perform calibration procedure as noted in

Factory Service Operations - Calibration (9-FS), page 70. Alternatively,

“stepping” through one of the calibration procedures clears the error flag,

but does NOT validate the calibration accuracy in any manner.

MANUAL CONTROL

The controller can be transferred between Automatic Control (closed loop; On/Off or PID control) and Manual Control (open loop; where the control does not work from the setpoint or process feedback.)

Manual operation provides percentage of control of the main output (per the direct or reverse action configured in Output Parameter 2-OP OPAC) from 0 to +100% power. When A2 is configured for cooling (O2), Manual operation still provides 0 to 100% powerto themain(O1)outputandprovides percentage of control to cooling (O2) output from -100% to 0% power. (Negative percent power is positive cooling (O2) percent power.)

To allow front panel switching between control modes, the Transfer Parameter (trnF) must be enabled (Enbl) in Lockout Module(3-LC).The user can then select Manual Control from the Hidden Function Mode using Transfer Parameter (trnF). The percentoutput power is then adjustedwith the Up and Down arrow buttons in the Normal Display Mode with the %P and MN annunciators illuminated.

In Time Proportional output control (relay, logic, or triac) the percent output power is converted into output on time using Time Proportioning Cycle Time (CYCt) value in Output Parameter Module (2-OP). For example with 4 cycle time and 75%power, the output will be on (4 x.75) for 3 seconds and off for 1 second.

In Linear DC output control (0-10 VDC or 0/4-20 mA), the percent output power is converted into a linear value per theLinear output low scaling value (AnLO) and Linear output high scaling value (AnHI) in Output Parameter Module (2-OP). For example with 0 VDC (scaled 0.0%) to 10 VDC (scaled 100%) and 75% power, the linear DC output will be 7.5 VDC.

When transferring the controller mode from or to Automatic Control, the controlling outputs remain constant, exercising true “bumpless” transfer. When transferring from Manual to Automatic, the power initially remains steady but integral actions corrects (if necessary) the closed loop power demand at a rate proportional tothe Integral Time. Thelow (OPLO) and high (OPHI) output power limits in OutputParameter(2-OP) are ignored when the controller is in Manual Control.

-47-

ON/OFF CONTROL

Single Output

The controller operates in ON/OFF Control when the Proportional Band is set to 0.0%.In this control, the process will constantly oscillate about the setpoint value. The amount of ON/OFF Control Hysteresis (CHYS) in Output Parameter Module (2-OP), together with the process characteristics determines the period and amplitude of the oscillations. Larger values of hysteresis increase both the amplitude and period of oscillations but also reduce the number of output switching cycles.

The Control Action (OPAC) in Output Parameter Module (2-OP) can be set to reverse (rEv) for heating (output on when below the setpoint) or direct (drct)for cooling (output on when above the setpoint) applications.

In controllers with operating system software revision earlier than V4.x, the ON/OFF Control Hysteresis value is not balanced around the setpoint value. In these controllers, the Hysteresisis totally added to the setpoint in reverse action and totally subtracted from the setpoint in direct action. The revision number of the controller’s operating system software is shown in the secondary (bottom) display during controller power up.

Figure 22, Output 1 (O1) ON/OFF Control

Software Revision V4.0 or Later

Figure 23, Output 1 (O1) ON/OFF Control

Software Revision V3.x or Earlier

Dual Output

For heat and cool systems, the heat (O1) and cool (O2) outputs can be used together in the ON/OFF control. For this operation, set the Cooling Relative Gain (GAN2) in CoolingParameterModule(5-02) to 0.0. This placesO2 into ON/OFF Control. In this mode, the ON/OFF Control Hysteresis (CHYS) in Output Parameter Module (2-OP) applies to both O1 and O2. The Heat/Cool Deadband (db-2) in Cooling Parameter Module (5-02) sets the amount of operational deadband or overlap between the outputs.

For these applications, the Control Action (OPAC) in Output Parameter Module (2-OP) is normally set to reverse (rEv). This sets O1 into reverse (heat) with O2 always in direct (cool). Cooling output for the P48 is referred to as the second control output.

In controllers with operating system software revision lower than 4.0, the ON/OFF Control Hysteresis value is not balanced. In these controllers, the Hysteresis is totally added or subtracted from the setpoint. The revision number of the controller’s operating system software is shown in the secondary (bottom) display during controller power up.

AUTO-TUNE FOR PID CONTROL

Auto-Tune is a user initiated function in which the controller automatically determines the PID settings based upon the process characteristics. During Auto-Tune, the controller temporarily causes the system to oscillate by cycling the output power from 0 to 100%. The nature of these oscillations determines the settings of the controller’s parameters.

Auto-Tune Code. A code setting of zero gives the fastest response with possible overshoot, and a code of two gives the slowest response with minimum overshoot.

Figure 28, Auto-Tune Code

Note: If the induced oscillations caused by Auto-Tune can cause system

problems or are otherwise unacceptable, the Manual Tuning Procedure can

be used as a tuning alternative.

Prior to initiating Auto-Tune, it is essential that the controller be configured to the application. In particular, Control Hysteresis (CHYS) and Auto-Tune code (tcod) must be set in the Output Parameters section. Auto-Tune requires thehysteresis setting to beabove the process noisefloor; generally, 2 - 5 degrees or 1-2% of range is adequate. For most applications, the control hysteresis should beset at2 (factory setting). The Auto-Tune code may be set to yield the response characteristics shown in Figure 28,

Figure 29, Auto-Tune Operation

The following controller parameters are automatically adjusted by

Auto-Tune according to the characteristics of the process:

Proportional Band (ProP) Integral Time (Intt) DerivativeTime(dErt) Input Filter (Fltr) Output Power Dampening (OPdP)

As shown in Auto-Tune Operation, Figure 29, Auto-Tune Operation cycles the process at a control point 3/4 of the distance between the current process value (at the instant Auto-Tune is started) and the setpoint. The 3/4 control

-51-

point was selected to reduce the chance of overshoot at setpoint when Auto-Tuning at start-up. If Auto-Tuning from setpoint and overshoot is unacceptable, temporarily lower the setpoint by an amount of the oscillation and then Auto-Tune. Reset the setpoint tothe originalvaluewhen Auto-Tune is complete. After starting Auto-Tune, the secondary display indicates the current phase (Aut1, Aut2, Aut3, & Aut4). If the controller remains in an Auto-Tune phase unusually long, the process or connections may be faulty. Additionally, during Auto-Tune it is important that disturbances to the system be minimized, as these may have an effect on the parameter determination.

Initiate Auto-Tune

Auto-Tune may be initiated at start-up, from setpoint, or at any other

process point.

To Initiate Auto-Tune:

1. Make sure that Auto-Tuning is enabled in Lockouts Parameter Module (3-LC).

2. Place the controller into the Normal Display Mode.

3. Press P for 3 seconds from Normal Display Mode.

4. Scroll to “tUNE” by use of P, if necessary.

5. Select “YES” and press P.

Auto-Tune is initiated.

To Cancel Auto-Tune: (Old PID settings remain in effect). A) Make sure that Auto-Tuning is enabled in parameter lockouts module.

1. Place the controller into the normal display mode.

2. Press P for 3 seconds from normal display mode.

3. Scroll to “tUNE” by use of P, if necessary.

4. Select “NO” and press P.

5. Auto-Tune canceled.

B) Or reset the controller by disconnecting power.

Auto-Tune Of Heat/Cool Systems

During Auto-Tune of heat/cool systems, the controller switches the cooling output (O2) on and off in addition to the heat output (O1). The heat/cool overlap deadband parameter (db-2) determines the amount of overlap or deadband between the two outputs during Auto-Tune. For most applications, set this parameter to 0.0 prior to starting Auto-Tune. After the completion of Auto-Tune, this parameter may need to be reset.

It is important that externalload disturbances be minimized, and if present, other zone controllers idled as these may have an effect on the PID constant determination. The controller additionally sets the Cooling Relative Gain parameter (GAN2) for heat/cool systems.

Some water cooled processes exhibit an extreme non-linear gain characteristic. That is,the process cooling gainstarts very high andflattens out deeper into the cooling region. This effect may result in regular oscillations at setpoint as the controller applies heat to counteract the effect. These processes may benefit from a lower cooling fan setting and/or reduced water flow in the jacket or manifold. The process heat and cool gainsshould bebalanced as much as possible, and the controller gains adjusted to the process.

Auto-Tune Of Cascade Control

The following procedure may be used to tune cascaded controllers:

1. Place the Secondary controller into Local Setpoint mode and Manual

(USEr) mode of operation

2. Adjust output power level of the secondary until primary variable is close

to primary setpoint (5% of range).

3. Key-in secondary setpoint value equal to secondary process value.

4. Auto-Tune the secondary controller while in Local Setpoint mode.

5. Place the secondary controller into Remote Setpoint mode and Automatic

(Auto) mode of operation.

6. Auto-Tune the primary controller while the primary is in Automatic mode

of operation.

7. Initial tuning of system is complete.

After the process has stabilized, the primary and secondary may be

re-tuned in Automatic mode of operation. Normally, the primary requires

re-tuning whenever the secondary PID constants are changed.

Note: For Remote Setpoint controllers, the Auto-Tune control point is derived

from the Remote Setpoint when in Remote Setpoint mode and from the Local

Setpoint when in Local Setpoint mode.

PID CONTROL EXPLANATIONS

Proportional Band

Proportional band is defined as the “band” (range) the process changes to cause the percent output power to change from 0% to100%. The band may or may not becentered about thesetpoint value depending upon the steadystate requirements of the process. The band is shifted by manual offset or integral action (automatic reset) to maintain zero error. Proportional band is expressed as percent of input sensor range.

For T48, the ranges are fixed for the thermocouple and RTD types.

For P48, the range is set by the difference between “dSP2 and dSP1”.

Figure 30, Proportional Band

Example: Thermocouple type T with a temperature range of 600°C is used

and is indicated in degrees Celsius with a proportional band of 5%. This

yields a band of 600°C X 5% = 30°C.

The proportional band should be set to obtain the best response to a disturbance while minimizing overshoot. Low proportional band settings (high gain) result in quick controller response at expense of stability and increased overshoot. Settings thatare excessively low produce continuousoscillations at setpoint. High proportional band settings (low gain) result in a sluggish response with long periods of process “droop”. A proportional band of 0.0% forces the controller into ON/OFF control mode with its characteristic cycling at setpoint (See ON/OFF Control, page 48, for more information).

Integral Time

Integral time is defined as the time, in seconds, in which the output due to integral action alone equals the output due to proportional action with a constant process error. As long as a constant error exists, integral action repeats the proportional action each integral time. Integral action shifts the center point position of the proportional band to eliminate error in the steady state. The units of integral time are seconds per repeat.

Integral action (also known as “automatic reset”) changes the output power to bring the process to setpoint. Integral times that are too fast (small times) do not allow the process to respond to the new output value. This causes over-compensation and leads to an unstable process with excessive overshoot. Integral times that are too slow (large times) cause a slow response to steady state errors. Integral action may be disabled by settingthe timetozero.If timeis set to zero, the previous integral output power value is maintained.

If integral action is disabled, manual reset is available by modifying the output power offset (“OPOF” initially set to zero) to eliminate steady state errors. This parameter appears in unprotected parameter mode when integral time is set to zero. The controller has the feature to prevent integral action when operating outside the proportional band. This prevents “reset wind-up”.

Note: The Proportional band shift due to integral action may itself be “reset” by temporarily setting the controller into the ON/OFF control mode (proportional band =0)

Figure 31, Integral Time

-53-

Derivative Time

Derivative time is defined as the time, in seconds, in which the output due to proportional action alone equals the output due to derivative action with a ramping process error. As longas a ramping error exists, the derivativeaction is “repeated” by proportional action every derivative time. The units of derivative time are seconds per repeat.

Derivative action is used to shorten the process response time and helps to stabilize the process by providingan output based on the rate of change ofthe process. In effect, derivative action anticipates where the process is headed and changes the output before it actually “arrives”. Increasing the derivative time helps to stabilize the response, but too much derivative time coupled with noisy signal processes, may cause the output to fluctuate too greatly, yielding poor control. None or too little derivative action usually results in decreased stability with higher overshoots. No derivative action usually requires a wider proportional and slower integral times to maintain the same degree of stability as with derivative action. Derivative action is disabled by setting the time to zero.

Output Power Offset (Manual Reset)

If the integral time is set tozero(automaticreset is off), it may be necessary to modify the output power to eliminate errors in the steady state. The output power offset (OPOF) is used to shift the proportional band to compensate for errors in the steady state. Theoutput power offset (OPOF) parameter appears in the unprotected mode, if the integral time equals zero. If integral action (automatic reset) is later invoked, the controller continues from the previous output power offset and updates accordingly.

PID Adjustments

To aid in theadjustment ofthe PID parametersfor improvedprocess control, a chart recorder is necessaryto providea visual means of analyzing the process. Compare the actual process response to the PID response figures with a step change to the process. Make changes to the PID parameters in no more than 20% increments from the startingvalue and allow the processsufficient time to stabilize before evaluating the effects of the new parameter settings.

MANUAL TUNING FOR PID CONTROL

In some unusual cases, the Auto-Tune function may not yield acceptable control results. In this case, the controller can be manually tuned to optimize the PID setting according to the process and thedesired controlrequirements.

Manual Tuning Procedure

A chart recorder or data logging device is necessary to measure the time between process cycles.

1. Set theProportional Band (ProP) fromthe Unprotected Parameter Mode to

10.0% for T48 models and 100.0% for P48 models.

2. Set the Integral Time (Intt) and Derivative Time (dErt) to 0 seconds.

3. Set Output Power Dampening Time (OPdP) in Output Parameter Module

(2-OP) to 0 seconds.

4. Set Output Cycle Time (CYCt) in Output Parameter Module (2-OP) to no

higher than 1/10 of the process time constant (when applicable).

5. Place controller in Manual Control and set % Power from the Normal

Display Mode to drive the process value to the desired value. Make certain

that the controller can drive the process to the setpoint. Allow the process

to stabilize after setting the % Power.

6. Place controller into Automatic Control. If the process will not stabilizeand

starts to oscillate, set the Proportional Band 2xhigher andgoback to step 5.

7. If the process is stable, decrease Proportional Band setting by 2x and

change the setpoint value a small amount to excite the process. Continue

with this step until the process oscillates in a continuous nature.

8. Fix the Proportional Band to 3x thesetting thatjustcausedtheoscillations.

9. Set the Integral Time to 2x the period of the oscillations.

10. Set the Derivative Time to 1/8 (0.125) the Integral Time.

11. Set Output Power Dampening Time to 1/40 (0.025) the period of the

oscillation.

Note: This procedure is an alternate to the controller’s Auto-tune function. It

will not provide acceptable results if system problems exist.

-56-

REMOTE SETPOINT OPTION

A remote 0/4 to 20 mA analog input signal can be used to change the setpoint value. This input can be scaled over a process range independent of that of the system range. In operation, the front panel “MN” indicator illuminates for local setpoint operation and is off for remote setpoint operation. In either mode, the indicator flashes during Manual Mode. Filtering, ramp rate (velocity limiting), and local/remote transfer response options can be configured to suit the application. Local/Remote transfer operations are performed either externally (user input) or at the keypad.

If large changes in the remote setpoint signal result in undesirable controller performance, the remote setpoint can be velocity limited (ramped) by the setpoint ramp parameter (SPrP).

Similarly, if fluctuation in the remote setpoint signal also results in poor performance, the programmablefilter can be used to provide a steady setpoint to the controller. A unique feature of the filter is the filter band. Fluctuations that occur that are lessthanthe filter band value keep thefilterengaged, while fluctuations outside the filter band disable the filter. This action allows the controller to respond rapidly to large changes of the remote setpoint signal.

CASCADE CONTROL

External cascade control involves the use of two controllers, one of which

has a Remote Setpoint Input.

The outer loop controller (Primary controller) directs the setpoint of the inner loop controller (secondary controller) through the linear DC output. The secondary controllerhas a Remote Setpoint optionin order to receivethe directed setpoint. See Figure 35, Cascade Control, for more details.

Note: The Remote Setpoint of the secondary controller must be scaled prior to

tuning the controllers. Normally, the Remote Setpoint is scaled to equal the

actual process range of the secondary. Scaled in this way, the primary

controller can direct the setpoint of the secondary controller over its

operating range. Normally, the secondary controller is a faster control loop.

It is able to respond quickly to disturbances before they affect the primary

loop. Therefore, thecontrol quality of the primaryloopunder cascade control

is superior to that of a single loop controller.

SERIAL COMMUNICATIONS INTERFACE

RS-485 Serial Communications

The optional RS-485 serial communication interface provides two-way communication between the controller and other compatible equipment such as a printer, PLC, HMI, or a host computer. In multipoint applications, each controller can be configured with a unique node address ranging from 0-99. Through this serial interface, data from the controller can be interrogated or changed, alarm output(s) reset and Auto-tune invoked.

Since the same pair of wires are used for both transmit and receive, only one-way communication is possible at a time. The controller has a variable response time, to allow the host device adequate time to release the communication line after issuing a command to the controller.

Configuration Software

The Serial communications option is necessary to work with Red Lion Control’s Windows based SFCRM software. This software allows for easy controller parameter configuration by computer. These settings can be saved to a disk file for later use or used for multi-controller down loading. On-line help is provided within the software.

Controller Configuration

The controller’s serial communication format is configured in Serial Communication Program Module 6-SC using the front panel. Baud rate and character frame must be matched to the other communicating device. The node address parameter is a unique address number assigned to each slave unit on the bus.

Sending Commands And Data

When sending commands to the controller, a command string of ASCII characters must be constructed. The string varies in length depending on the nature of the command. At most, a command string consists of a Controller (Node) Address number (not required for address of 0), a Command Code character, a Register Identification character (for most commands), Numerical Data (if writing data to the controller) and ending with a string Terminator of “*” or “$”. The controller will not respond with an error message to invalid commands.

Sending Numeric Data

Data written to individual registers must be limited to the registers numerical data range (See Register Identification Table). If more digits are sent, the controller only accepts the last four digits of the numeric data. Negative numbers must have a minus sign. The controller ignores any decimal point and conforms the number to the register identification resolution. (Example: “25” is written to the proportional band register. The value recorded by the register is now 2.5. Ifa value of 25% is intended, write a value of 25.0 or 250.

Command Code Explanations

Controller (Node) Address: N

When more than one controller is on the serial communication bus, a

unique controller (node) address must be assigned to each unit. The address range extends from 0 to 99. This is defined in the controller configurations. To communicate with a specific controller, the address code N followed by the controller’s address value must start a command string.A controller with an address of 0 does not require the node address command. Controllers with an address greater than 0 willrespond to transmit commands by sending their address followed by the requested data.

-59-

Read Register Command Code: T

The Read Register command is used to read data from a register. This command must be followed by a Register IDcharacter.Infull response mode, the controller responds to this command by transmitting its Address (if greater than 0), corresponding register mnemonic and register data. In abbreviated response mode, the controller transmits data only. The response time to this command is controlled by the type of termination character. This is a single register response.

Write Register Command Code: V

The Write Register command is used to write data to a register. This command must be followed by a Register ID character and Numeric Data. A unique command line is required for each register write operation. No response occurs for invalid write operations. The Read Register command (T) can be used for readback verification.

Reset Alarm Command Code: R

The Reset Alarm command resets the alarm outputs. This command must be followed by a Register ID character (G for Alarm 1, and H for Alarm 2). This command does not alter the actual alarm mode or value setting.

Control Action Command Code: C

The Control Action command is used to affect certain controller operating modes.The registers used with this command are: Auto/Manual mode select, Auto-Tune mode select, andRemote Setpoint mode select. Afterthe Register ID character, either a “1” or “2” is sent to set a specific controller mode.

Block Read Register Command Code: P

The Block Read Register command is used to read data from multiple registers with a single command. With this command, if no register ID characters follow, the controller responds with register data that is preset by the Print Options parameter (Module 6-SC). This mode is useful for print ticket applications. However,if Register ID characters follow this command, the controller responds with register data indicated by the ID character field. This character ID field does not follow the normal Register ID format, but instead is a field composed of ASCII encoded bit mapped bytes. (See Block Read Command Register ID Table.)

Four of these field bytes are used in this format:

P<Byte1><Byte2><Byte3><Byte4>

Each byte represents a code that selects a register(s) for transmission. The Block Read Command Byte Table relates specific registers for reads to the field bytes.

Examples:

Print: Alarm 1 and Alarm 2 values (both are in Byte2 table)

Terminator:*or$

After a Read Register command is sent, the response time of the controller

is determined by the type of command terminator character. The “$” terminator causes a response time of 2 msec to 100 msec and the “*” terminator causes a response time of 100 msec to 200 msec. (The 2 msec delay allows for a two character transmission time at 9600 baud. ) The controller does not begin processingthecommandstring until the “$” or “*” isreceived. The Carriage Return <CR> and the Line Feed <LF> cause the controller to ignore the command string. When writing setpoint values, only values using the “*” terminator are saved to E

PROM memory.

Unique Register Explanations

Setpoint Ramp Using Automatic Setpoint Ramping Register: K

The controller’s Setpoint Ramp parameter provides a controlled rampwhen the setpoint value is changed. (The Setpoint Ramp value can be changed by using VK command.) When the setpoint value is changed,the controllerbegins to ramp from the existing value to the new target setpoint, at a rate set by this register. A value of zero in the Setpoint Ramp register disables ramping.

During the controlled ramp phase, the Integral Action is automatically disabled. This tends to reduce overshoot due to excessive integral build-up. The Integral Action automatically resumes at the end of the controlled ramp phase.

To terminate a ramp in progress, write 0 (zero) to the Setpoint Ramp register. This results in immediate control to the target setpoint.

Setpoint Ramp Using Periodic Setpoint Write Register: B

A host computer can command the setpoint value of the controller by writing new setpoint values based on clock ticks. In thismanner, the host has explicit control over setpoint values, ramp and hold phases.

During ramp phases, the Integral Action may lead to overshoot problems. In this case, the integral action may be slowed or completely disabled by setting the integral time register.

Periodic Setpoint Write Commands (E

In the case of periodically writing setpoint values to the controller (host is running a temperature/process profile), terminate the write command with the “$” terminator character. This instructs the controller to accept the setpoint value, but not to write thevalue toE cycling of the internal memory chip, which has a finite life-cycle rating (1 million typical). This rating should not be exceeded.

After power loss, the setpoint value written will be lost when using “$”. Termination of the setpoint write command with the “*” character instructs the controller to save the value to E value will be recalled after a power loss.

PROM memory. In this case, the setpoint

Heater Current Response: HC (T48 only)

The Heater Current register identifies whetherthe output ison or off at the time it is read. This is indicated by the three letter mnemonic HCN or HCF (N=on, F=off). For example, when a read occurs while the output is off, this response occurs: “HCF x.x”. This indicates that the heater current reading is with the main output switchedoff. If the controller responds with“HCNx.x”, the reading is with the main output switched on. The output status register is not synchronous in time with heater current register.

Output Status: W

The Output Status register indicates the present status of the controller’s discrete alarm outputs (coils). This is a read only register. The controller responds with OST followed by a field consisting of 4 bytes. The bytes represent the status of the outputs in the following order: main output O1, cooling/ secondary output (O2), alarm 2 output (A2), alarm 1 output (A1). When the output is on, the corresponding byte is “1.” When the output is off, the corresponding byte is “0”.

Communication Format

Data is transferred from the controller over a serial communication channel. In serial communications, the voltage is switched between a high and low level at a predetermined rate (baud rate) using ASCII encoding. The receiving device reads the voltage levels at the same intervals and then converts the number back to a character.

The table lists the required voltage levels at the receiver for RS485 interface.

Logic RS485 Interface State

1 a-b <-200 mV mark (idle)

0 a-b >+200 mV space (active)

Data is transmitted one byte at a time. Each ASCII character is “framed” with a beginning start bit, an optional error detection parity bit and one or more ending stop bits.

-62-

Figure 36, Character Frame

To allow the host adequate time to release the bus after a transmission, the response time of the controller is programmable. The controller utilizes a receiver design that interprets a mark condition for open connections.

Start Bit and Data Bits

Data transmission always begins with the start bit. The start bit signals the receiving device to prepare for reception of data. One bit period later, the least significant bit of the ASCII encoded character is transmitted, followed by the remaining data bits. The receiving device then reads each bit position as it is transmitted. Since the sending and receiving devices operate at the same transmission speed (baud rate), the data is read without timing errors.

Parity Bit

After the data bits, theparitybit is sent. The transmitter sets the paritybit to a zero or a one, so that the total number of ones contained in the transmission (including the parity bit itself) is either even or odd. This bit is used by the receiver to detect one bit errors occurring in the transmission. Given this limitation, the parity bit is often ignored by the receiving device. The controller ignores the parity bitof incomingdata and sets the parity bit toodd, even or none (mark parity) for outgoing data.

Stop Bit

The last character transmitted is the stop bit. The stop bit provides a single bit period pause to allow the receiverto prepare to re-synchronize to the start of new transmission (start bit of next byte). After the stop bit, the receiver continuously looks for the occurrence of the next start bit.

Command Response Time

The controller can only receive ortransmitdata at any one time (half-duplex operation). If bus activity, such as another command, occurs before the controller has ended its transmission, garbled data will result. When sending commands and data to the controller, timing restrictions are imposed when sending another command afterwards. This allows enough time for the controller to process the command and prepare for the next command. If the timing requirements are not obeyed, lost transmissions may result.

Troubleshooting Serial Communications

If problems are encountered when interfacing the controller(s) and host

device or printer, the following check list can be used tohelp findasolution.

1. Check all wiring. Proper polarity of all devices on the serial loop must be observed. Refer to previous application examples.

2. Check the controller’s communication format in module 6-SC. Make sure all devices on the serial loop are configured with the same communication format.

3. Check the requesting device constructed command string format.

4. When sending commands to the controller, an asterisk “*” or dollar sign “$” must terminate the command. Make sure a carriage return or line feed does not follow the command terminator.

5. Check the controller’s unit address in module6-SC. It should be zero if the address command is not used in the command string for single controller configurations. In multiple controller configurations, make sure each controller has a unique unit address.

6. Initiate transmissions from the controller by programming the User Input for PrNt in module 1-IN for print and programming module 6-SC at PoPt set INP (input) to YES. As long as the user input is connected to common, controller data will be sent.

7. With two-way communications or multiple controller configurations, make sure only one device is communicating at a time.

8. If all of the above has been done, try reversing the polarity of the serial wires at host device or printer. Some devices have reversed polarity.

Error Flag E-CL

If error flag “E-CL” appears at power-up, a loss of calibration parameters due to noise spikes has occurred. Entering code 77 twice in Factory Service Operations Module (9-FS) erases the controller calibration values and defaults the valuesto nominal settings. Readingerrors of ±10% mayresult. It is recommended that the controller be fully re-calibrated. If using thermocouple only, the RTD calibration need not be performed.

Note: The “E-CL” flag may be cleared by “stepping” through cold junction or

linear output calibration procedures without the need to change any

calibration values. A

10% reading error will still exist.

Calibration For T48

When re-calibration is required (generally every two years), this procedure should be performed by qualified technicians using appropriate equipment. Equipment source accuracy of 0.03% or better is required.

The procedure consists of: applying accurate mV signals, setting the thermocouple cold junction temperature, and applying precision resistance, among others. Allowa 30 minute warm-up period beforestarting this procedure. Do not use thermocouple wire for the Millivolt or RTD ohms Calibration.

This procedure may be aborted by disconnecting power to the controller before exiting the configuration mode. The existing calibration settings remain in affect.

Note: After completing any of the calibration sequences, the controller defaults

the input sensor type to thermocouple type “J” (tc-j). Be sure to set input

sensor for proper type. Note: The controller must be restored to normal display mode before any data

is stored.

REPLACEABLE OUTPUT BOARD DESCRIPTION

Output Board

The controller is supplied with an output board (relay, logic/SSR or triac) installed. The output board is configured for the type of Main Control and Alarm Output based upon the model number ordered. The output board is field replaceable in many models. (For models where the output board is not replaceable, the controller must be returned to the factory for output board repair.) See Ordering Information, page 81, for available models.

Replacing Output Board

1. Remove the bezel assembly. (See Removing Bezel Assembly, page 3).

2. Lift up on the top bezel board latch while gently pulling out on the

bezel/display board assembly. Do NOT remove the display board from

the bezel.

3. Remove the outputboard by pulling it away fromtheother boards. Replace

the output board by aligning the board to board connector. Be certain the

connector is fully mated.

4. Connect thebezel/displayboard assembly by guiding the boardends into the

bezel latches. Slide the assembly on evenly until thedisplay board connector

is completely engaged and bezel latches are fully seated onto the boards.
